Abstract
The paper presents a procedure for the identification of semi-rigid end connectionsof beam/column elements in frame structures. The technique relies on an explicitrelationship between second order moments of nodal stationary response underwhite noise and element end flexibilities. Such relationship, albeit approximate, isvery accurate when the element stiffness matrix is properly disassembled and can besuccessfully employed inside the objective function to be minimized so to estimatethe unknown parameters.File in questo prodotto:
